katoftw Posted January 16, 2014 Share Posted January 16, 2014 I'm sure many dads/grandads know this story. the kids although love playing with the trains, only know how to turn the Kato throttle all the way to max. So I had an idea that I purchase the DC cable extensions and cut them up and put some form of resistor soldered into the wiring, that I could prevent them from running the trains so fast. And then it is dads turn, disconnect the resistor cable extension. Anyone done it? Or something similar. One day I will get the digitrax Zephur, and it has the 50%/75% power control of the boost controller. But until then, I need a solution. The is only so little time before a Shinkansen derailment is fatal. Link to comment
kvp Posted January 16, 2014 Share Posted January 16, 2014 Yes, at shows sometime the lego club i'm railroading with sets up a controller for the kids. I made a diode chain, that can be inserted serially after the controller. It consists of diodes connected together back to back. Each normal diode pair takes 0.7V from the output. This works for any kind of controller, even for pwm and dcc. (with dcc this is used to get a too high voltage booster output down to something safe for N and Z trains) ps: Actually it is possible to connect a rotary switch in a way that allows cutting out diodes one by one, so the output can be set without changing the wiring. 1 Link to comment

Davo Dentetsu Posted June 15, 2014 Share Posted June 15, 2014 Blimey, I know some of our senior citizens (or those who should know better anyway :P ) gun their stuff to the max. Not just the non-bearded of our society that does this. :D Link to comment
cteno4 Posted June 15, 2014 Share Posted June 15, 2014 (edited) Girls tend to be the speed demons at the shows where we have throttles out for the public to run! We have the same issue and been meaning to do either a little diode plug strip like KVM mentioned or a fancier adjustable throttle. One idea was to be simple and just put a big variac ac rheostat onto the wall wart to dim the power down. Only works as I have a couple of these laying around...

katoftw Posted January 16, 2015 Author Share Posted January 16, 2015 I wanted to revisit this. Do you think I could use a dimmer switch from a 12V-24V light system? Link to comment
kvp Posted January 16, 2015 Share Posted January 16, 2015 This depends on the circuit and the controller in use. In case they are not compatible, you could end up burning one or both. Link to comment

Mudkip Orange Posted January 16, 2015 Share Posted January 16, 2015 In a previous lifetime, when I did DJ setups, I'd run the output from the console mixer through another mixer off to the side before it hit the speakers. Then when every DJ wants to turn it up just a little bit more, I can turn it down just a little bit more, and the Mackies live to see another day. Link to comment
cteno4 Posted January 17, 2015 Share Posted January 17, 2015 One of our members is experimenting with changing the limiting resistor in a kato throttle to reduce the top voltage. Jeff Link to comment
